Traveling from Texas to New Mexico on vacation

Does anyone know the regulations around driving into NM with a handgun in the car. The driver does not have a CHL.

I could tell you what I think but it would be better for you to look up the laws. There are several websites produced by the state of NM. Look at this link about half way down. Hope this helps! http://www.dps.nm.org/lawEnforcement/ccw/ccwFaq.php
